X-tendo (eXTENDing the energy performance assessment and certification schemes via a mOdular approach) is an EU Horizon 2020 project, examining 10 features of the next generation of energy performance certificates (EPCs).

It will develop a toolbox to assist the implementation of the features into existing EPC schemes, to provide public authorities with improved compliance, reliability, usability and convergence of the next generation of energy performance assessments and certification.

As part of a consortium of 13 organisations from nine European countries, which together represent 40% of the EU building stock, Energy Saving Trust is leading on the work package testing the innovative indicators and data handling approaches through a selection of test projects. These will demonstrate the potential of the toolbox to deliver more reliable EPC schemes across the EU.

The features being tested are:

  • smart readiness
  • comfort
  • outdoor air pollution
  • real energy consumption
  • district heating
  • EPC databases
  • building logbook
  • tailored recommendations
  • financing options
  • one stop shops

In addition, due to our expertise in running the EPC Register for Scotland and the Scottish Government’s Home Energy Scotland programme, Energy Saving Trust is participating as an Implementing Partner testing the methodologies for the tailored recommendations and one stop shops features.
